Benjamin ★★★★★

Upgraded my R8 mini mill last weekend and the 3MT spindle fit perfectly with the included spacing ring. The instructions made the whole conversion straightforward and I was back to making chips in under an hour.

Benjamin ★★★★★

The double spindle gear engaged perfectly with my mill's existing mechanism, making the swap straightforward. The included instructions were clear enough for a first-time spindle conversion.

Isabella ★★★★★

I spent a Saturday afternoon installing this kit, and having the spacing ring included saved me a trip to the hardware store for shims. It converted my old mill over to the 3MT spindle without any guesswork.
